FlashPunk

From Flash Game Dojo

FlashPunk is a free ActionScript library, created by Chevy Ray Johnston, designed for developing 2D Flash games. Its goal is to provide a fast, clean framework to prototype and develop games in. This means that most of the dirty work (timestep, animation, input, and collision to name a few) is already coded and ready to go, allowing more time and energy to concentrate on design and testing. FlashGameDojo's wiki provided a set of useful snippets and tutorials for FlashPunk users to browse through.
